Mechanical Energy
Definition of Energy
-
Kinetic energy (KE) is the energy of a moving object because of its motion.
The moving object depends on the objects mass and its speed
Gravitational potential energy (GPE) is the energy of an object due to its position above Earth’s surface.
Elastic potential energy (EPE) is potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring.

Potential Energy (PE)
Gravitational Potential Energy
GPE = mgh
m = mass [kg]
g = gravitational acceleration [m/s2] = 9.81 m/s2
h = height [m]
GPE = gravitational potential energy [J]
-
Elastic Potential Energy
EPE = ½ kx2
k = spring constant [N/m]
x = displacement of the spring from neutral position [m]
EPE = elastic potential energy [J]
